ところで as ところ + で A sentence from this > **** strikes me as a little different from how the collocation is normally used, and amenable to being interpreted as a combination of two separate elements + , where the seems more like , as indicating a method to do something. Though it is possible too to parse this as a normal one expressing the time relation between two actions (→), that's a somewhat inadequate construal for me. A search in BCCWJ yielded results that are disparate, uncomparable from the sentence above, so I'm not certain about my understanding of and guessing on this sentence, including this .

It means more literally _at the place where_ rather than temporal order. But the _place_ is an abstract location/realm.

Literally speaking, the sentence says _Shinto 'works' at the place where death is excluded_. More idiomatically, it says that Shinto's rituals/teachings etc. assume absence of death or simply paraphrases that Shito does not treat death as claimed in other parts.
